What type of cell is seen here?
what kind of muscle is seen here?
what distinctive feature is seen?
what molecular structure facilitates communication between cells (aka efficient electrical signal transmission)?
what type of cells are seen here?
what structure is seen here? Jusitfy your answer.
What is the main tissue type of the structure?
valve. It is anchored to cardiac muscle tissue that is darker staining.
the valve is made of dense connective tissue usually found in the cardiac skeleton
Name the 5 visible orifices left to right, top to bottom:
left atrium, pulmonary artery, aorta, left ventricle, right ventricle
what two layers are visible in the vessel? (the lumen is at the base of this picture)
what are the darkest staining lines?
If the top visible layer is the largest in this vessel, is it an artery or a vein?
- media at the top, intima at the bottom (with line of simple squamous endothelium at the bottom)
- the dark staining lines are the elastic membranes
- if the media is the largest, this is an elastic artery
Is this an artery or a vein? What is the prominent feature?
This is a vein because the adventitia is largest (dark intima, lighter media, longitudinal cross section of smooth muscle in adventitia)
What vessels are depicted here? How can you tell?
Vein to left, artery to right. Usually beside each other. Vein is irregular, artery is a circle.
what structure is depicted here?
What type of capillary is depicted here?
A discontinuous capillary (or sinusoid)
What two vessels are depicted here?
artery with more smooth muscle to left, vein to right.
large, elastic artery
verhoff stain of aorta
name 2 vessels
extremely thick tunica adventitia
Normal aortic valve with three thin, delicate leaflets, empty sinuses of Valsalva and tight approximation of the
leaflets in the closed position
Mitral Valve (gross photographs). Fig. 1 is viewed from above from the atrium.
